BACKGROUND OF THE INVENTION

A. Field of the Invention

The invention relates to the field of plant genetics and, more specifically, to the development of carrot plants having increased lycopene content.

B. Description of Related Art

Carrot (Daucus carota var sativus), a member of the Umbelliferae family, is one of the most important root crops and is grown on over 100,000 hectares worldwide. Carrots provide an excellent source of various vitamins and minerals, including vitamin A (beta-carotene), as well as dietary fiber content in animal diets. Breeding efforts over the last half century have resulted in a 75% increase in the beta-carotene content in cultivated carrots. Recently, interest in the nutritional value of other carrot pigments, such as xanthophylls, lycopene, anthocyanins, and other phytochemicals, has increased. Despite recent breeding efforts, there remains a need for the development of carrots having increased levels of carotenoids, other than beta-carotene, such as lycopene.

In general, the goal of vegetable breeding is to combine various desirable traits in a single variety/hybrid. Such desirable traits may include greater yield, resistance to insects or pests, tolerance to heat and drought, better agronomic quality, higher nutritional value, growth rate and fruit properties.

Breeding techniques take advantage of a plant's method of pollination. There are two general methods of pollination: a plant self-pollinates if pollen from one flower is transferred to the same or another flower of the same plant or plant variety. A plant cross-pollinates if pollen comes to it from a flower of a different plant variety.

Plants that have been self-pollinated and selected for type over many generations become homozygous at almost all gene loci and produce a uniform population of true breeding progeny, a homozygous plant. A cross between two such homozygous plants of different varieties produces a uniform population of hybrid plants that are heterozygous for many gene loci. Conversely, a cross of two plants each heterozygous at a number of loci produces a population of hybrid plants that differ genetically and are not uniform. The resulting non-uniformity makes performance unpredictable.

The development of uniform varieties often involves the development of homozygous inbred plants, the crossing of these plants, and the evaluation of the crosses. Pedigree breeding and recurrent selection are examples of breeding methods that have been used to develop inbred plants from breeding populations. Those breeding methods combine the genetic backgrounds from two or more plants or various other broad-based sources into breeding pools from which new lines are developed by selfing and selection of desired phenotypes. The new lines are evaluated to determine which of those have commercial potential.

Carrots (Daucus carota) are one of the most important root crops and is grown on over 100,000 hectares worldwide. There are two main types of cultivated carrots. Eastern/Asiatic carrots are often called anthocyanin carrots because of their purple roots, although some have yellow roots. They typically have pubescent leaves giving them a gray-green color and bolt easily. They have slightly dissected leaves with branched roots and are an annual plant. Western or carotene carrots typically have orange, red or white roots. These carrots were most likely derived from the first group by selection among hybrid progenies of yellow Eastern carrots, white carrots and wild subspecies grown in the Mediterranean. The leaves are generally strongly dissected with unbranched roots and bright green, sparsely hairy foliage and are biennial.

The biennial carrot is a plant that only flowers every two years. In the first year the plant produces the edible root and a leafy top. If a carrot plant is left in the ground for another year, aided by a resting and cold vernalization period, it flowers and seeds are produced. Sexual reproduction in carrots can therefore be carried out as with other flowering plants.

The Western carrot is the most popular carrot and is sub-divided into three groups: 1) short-rooted varieties that mature more quickly; such as Amsterdam Forcing, Tiana, Early French Frame, Early Nantes, Champion Scarlet Horn; 2) medium-rooted varieties, which are the most common type of commercially grown carrots and include varieties such as Mokum, Flakkee, Autumn King, Chantenay Red Cored, Royal Chantenay; and 3) long-rooted varieties, such as New Red Intermediate and Saint Valery.

Carrots are widely used as a fresh market or processed product. As a crop, carrots are grown commercially wherever environmental conditions permit the production of an economically viable yield. Carrots are highly regarded for their nutritional value and their storability. Carrots provide an excellent source of various vitamins and minerals, including vitamin A (beta-carotene), as well as dietary fiber content. Recently, interest in the nutritional value of other carrot pigments, such as xanthophylls, lycopene, anthocyanins, and other phytochemicals, has increased.

Historically, most carrot breeding methods involved mass selection and pedigree selection resulting in a great number of open-pollinated carrot varieties (Stein and Nothnagel, 1995). The first carrot hybrids were sold in the 1960s in the United States following the detection and analysis of male sterility in carrot by Thompson (1961) and Hanschke and Gabelman (1963). Hybrid breeding in carrot is generally based on two systems of cytoplasmic male sterility (CMS) with different genetic backgrounds and origin: “brown anther” type and “petaloid” type (Stein and Nothnagel, 1995). A third CMS system has been detected in an alloplasmic form originating from a cross between the wild carrot D. carota gummifer Hook. fil. and the cultivated carrot D. c. sativus Hoffm. (Nothnagel, 1992).

While breeding efforts to date have provided a number of useful carrot lines with beneficial traits, there remains a great need in the art for new lines with further improved traits. Such plants would benefit farmers and consumers alike by improving crop yields and/or quality.

SUMMARY OF THE INVENTION

The present invention relates to carrot lines having roots containing increased levels of lycopene, as well as containers of such carrots. The present invention also relates to parts of carrot plants from lines having roots with increased lycopene content, including seeds capable of growing carrot plants with increased root lycopene content.

The present invention also provides a seed of a carrot plant capable of producing a hybrid plant comprising roots having a lycopene content of at least 100 ppm, where a population of about 10 carrots contains an average lycopene content of between about 100 ppm and about 250 ppm.

The present invention also provides a method of producing a hybrid carrot seed comprising crossing a female parent having a lycopene content between about 100 ppm and about 200 ppm having cytoplasmic male sterility with a male carrot line having a lycopene content between about 100 ppm and about 200 ppm, and obtaining F₁ seed.

In still another aspect, the present invention is exemplified by plants or seeds of a carrot variety selected from red carrot hybrid 0710 0325, red carrot hybrid 0710 0339, red carrot hybrid 0710 0346, red carrot hybrid 710313, red carrot hybrid 710305, red carrot hybrid 710316, red carrot hybrid 710319, red carrot hybrid 710311, red carrot hybrid 710304, red carrot hybrid 710310, red carrot hybrid 710303, line RN 71-4963C, line RN 71-4904C, line RF 71-4911A, line RF 71-4912A, line RIF 71-4966C, line RIF 71-4967B, and line RIF 71-4968B. representative seeds of such varieties have been deposited with the ATCC as set forth herein below. As used herein, a plant of the invention includes any such plants.

In yet a further aspect, the present invention also provides hybrid carrot cultivar having a root comprising an increased lycopene level, where the lycopene content is measured as an average lycopene content of a plurality of roots obtained from the hybrid carrot cultivar compared to an average lycopene content of carrot roots obtained from Kintoki open pollinated variety carrots.

In another aspect, the present invention provides a carrot plant of the invention, as well as carrot plants having all the physiological and morphological characteristics of a plant of the invention. Parts of the carrot plant of the present invention are also provided, for example, including pollen, an ovule, a fruit, and a cell of the plant.

The carrot seed of the invention may be provided as an essentially homogeneous population of carrot seed of a plant of the invention. Essentially homogeneous populations of seed are generally free from substantial numbers of other seed. Therefore, seed may be defined as forming at least about 97% of the total seed, including at least about 98%, 99%, or more of the seed. The population of carrot seed may be particularly defined as being essentially free from hybrid seed. The seed population may be separately grown to provide an essentially homogeneous population of carrot plants of the invention.

In another aspect of the invention, a plant of the invention comprising an added heritable trait is provided. The heritable trait may comprise a genetic locus that is a dominant or recessive allele. In one embodiment of the invention, a plant of the invention is defined as comprising a single locus conversion. In specific embodiments of the invention, an added genetic locus confers one or more traits such as, for example, herbicide tolerance, insect resistance, disease resistance, and modified carbohydrate metabolism. The trait may be, for example, conferred by a naturally occurring gene introduced into the genome of the line by backcrossing, a natural or induced mutation, or a transgene introduced through genetic transformation techniques into the plant or a progenitor of any previous generation thereof. When introduced through transformation, a genetic locus may comprise one or more transgenes integrated at a single chromosomal location.

In another aspect of the invention, a tissue culture of regenerable cells of a plant of the invention is provided. The tissue culture will preferably be capable of regenerating plants capable of expressing all of the physiological and morphological characteristics of the line, and of regenerating plants having substantially the same genotype as other plants of the line. Examples of such physiological and morphological characteristics include those traits set forth in the tables herein. The regenerable cells in such tissue cultures may be derived, for example, from embryos, meristems, cotyledons, pollen, leaves, anthers, roots, root tips, pistil, flower, seed and stalks. Still further, the present invention provides carrot plants regenerated from a tissue culture of the invention, the plants having all the physiological and morphological characteristics of a plant of the invention.

In yet another aspect of the invention, processes are provided for producing carrot seeds, plants and fruit, which processes generally comprise crossing a first parent carrot plant with a second parent carrot plant, wherein at least one of the first or second parent carrot plants is a plant of the invention. In one embodiment, the plant is selected from a line designated RN 71-4904C, RF 71-4911A, RF 71-4912A, RIF 71-4966C, RIF 71-4967B, or RIF 71-4968B. These processes may be further exemplified as processes for preparing hybrid carrot seed or plants, wherein a first carrot plant is crossed with a second carrot plant of a different, distinct line to provide a hybrid that has, as one of its parents, a carrot plant line provided herein. In these processes, crossing will result in the production of seed. The seed production occurs regardless of whether the seed is collected or not.

In one embodiment of the invention, the first step in “crossing” comprises planting seeds of a first and second parent carrot plant, often in proximity so that pollination will occur for example, mediated by insect vectors. Alternatively, pollen can be transferred manually. Where the plant is self-pollinated, pollination may occur without the need for direct human intervention other than plant cultivation.

A second step may comprise cultivating or growing the seeds of first and second parent carrot plants into plants that bear flowers. A third step may comprise preventing self-pollination of the plants, such as by emasculating the male portions of flowers, (i.e., treating or manipulating the flowers to produce an emasculated parent carrot plant). Self-incompatibility systems may also be used in some hybrid crops for the same purpose. Self-incompatible plants still shed viable pollen and can pollinate plants of other varieties but are incapable of pollinating themselves or other plants of the same line.

A fourth step for a hybrid cross may comprise cross-pollination between the first and second parent carrot plants. Yet another step comprises harvesting the seeds from at least one of the parent carrot plants. The harvested seed can be grown to produce a carrot plant or hybrid carrot plant.

The present invention also provides the carrot seeds and plants produced by a process that comprises crossing a first parent carrot plant with a second parent carrot plant, wherein at least one of the first or second parent carrot plants is a plant of the invention. In one embodiment of the invention, carrot seed and plants produced by the process are first generation (F₁) hybrid carrot seed and plants produced by crossing a plant in accordance with the invention with another, distinct plant. The present invention further contemplates plant parts of such an F₁ hybrid carrot plant, and methods of use thereof. Therefore, certain exemplary embodiments of the invention provide an F₁ hybrid carrot plant and seed thereof. For example, the invention provides plants and seeds of hybrid carrot variety 0710 0325, 0710 0339, or 0710 0346.

In still yet another aspect of the invention, the genetic complement of a carrot plant of the invention are provided. The phrase “genetic complement” is used to refer to the aggregate of nucleotide sequences, the expression of which sequences defines the phenotype of, in the present case, a carrot plant, or a cell or tissue of that plant. A genetic complement thus represents the genetic makeup of a cell, tissue or plant, and a hybrid genetic complement represents the genetic make up of a hybrid cell, tissue or plant. The invention thus provides carrot plant cells that have a genetic complement in accordance with the carrot plant cells disclosed herein, and plants, seeds and plants containing such cells.

Plant genetic complements may be assessed by genetic marker profiles, and by the expression of phenotypic traits that are characteristic of the expression of the genetic complement, e.g., isozyme typing profiles. It is understood that a plant of the invention could be identified by any of the many well known techniques such as, for example, Simple Sequence Length Polymorphisms (SSLPs) (Williams et al., 1990), Randomly Amplified Polymorphic DNAs (RAPDs), DNA Amplification Fingerprinting (DAF), Sequence Characterized Amplified Regions (SCARs), Arbitrary Primed Polymerase Chain Reaction (AP-PCR), Amplified Fragment Length Polymorphisms (AFLPs) (EP 534 858, specifically incorporated herein by reference in its entirety), and Single Nucleotide Polymorphisms (SNPs) (Wang et al., 1998).

In still yet another aspect, the present invention provides hybrid genetic complements, as represented by carrot plant cells, tissues, plants, and seeds, formed by the combination of a haploid genetic complement of a carrot plant of the invention with a haploid genetic complement of a second carrot plant, preferably, another, distinct carrot plant. In another aspect, the present invention provides a carrot plant regenerated from a tissue culture that comprises a hybrid genetic complement of this invention. In still yet another aspect, the invention provides a plant of a carrot line, the roots of said plant exhibit a combination of traits comprising an average lycopene content from about 110 ppm to about 250 ppm and an average brix content from about 11° brix to about 20° brix, wherein the expression of the combination of traits is controlled by genetic means for the expression of the trait found in a carrot variety provided herein, including one or more of red carrot hybrid 0710 0325, red carrot hybrid 0710 0339, red carrot hybrid 0710 0346, red carrot hybrid 710313, red carrot hybrid 710305, red carrot hybrid 710316, red carrot hybrid 710319, red carrot hybrid 710311, red carrot hybrid 710304, red carrot hybrid 710310, red carrot hybrid 710303, line RN 71-4963C, line RN 71-4904C, line RF 71-4911A, line RF 71-4912A, line RIF 71-4966C, line RIF 71-4967B, and line RIF 71-4968B.

In still yet another aspect, the invention provides a method of determining the genotype of a plant of carrot line or variety disclosed herein comprising detecting in the genome of the plant at least a first polymorphism. The method may, in certain embodiments, comprise detecting a plurality of polymorphisms in the genome of the plant. The method may further comprise storing the results of the step of detecting the plurality of polymorphisms on a computer readable medium. The invention further provides a computer readable medium produced by such a method.

In still yet another aspect, the present invention provides a method of producing a plant derived from a line or variety disclosed herein the method comprising the steps of: (a) preparing a progeny plant derived from the line or variety, wherein said preparing comprises crossing a plant of a plant of the invention with a second plant; and (b) crossing the progeny plant with itself or a second plant to produce a seed of a progeny plant of a subsequent generation. In further embodiments, the method may additionally comprise: (c) growing a progeny plant of a subsequent generation from said seed of a progeny plant of a subsequent generation and crossing the progeny plant of a subsequent generation with itself or a second plant; and repeating the steps for an additional 3-10 generations to produce a plant derived from the line or variety. The derived plant may be an inbred line, and the aforementioned repeated crossing steps may be defined as comprising sufficient inbreeding to produce the inbred line. In the method, it may be desirable to select particular plants resulting from step (c) for continued crossing according to steps (b) and (c). By selecting plants having one or more desirable traits, a plant is obtained which possesses some of the desirable traits of the line as well as potentially other selected traits.

In another aspect of the invention, a plant of a carrot line or variety comprising an added heritable trait is provided. The heritable trait may comprise a genetic locus that is a dominant or recessive allele. In one embodiment of the invention, a plant of the invention is defined as comprising a single locus conversion. In specific embodiments of the invention, an added genetic locus confers one or more traits such as, for example, herbicide tolerance, insect resistance, disease resistance, and modified carbohydrate metabolism. The trait may be, for example, conferred by a naturally occurring gene introduced into the genome of the hybrid by backcrossing, a natural or induced mutation, or a transgene introduced through genetic transformation techniques into the plant or a progenitor of any previous generation thereof. When introduced through transformation, a genetic locus may comprise one or more transgenes integrated at a single chromosomal location.

In another aspect of the invention, a tissue culture of regenerable cells of a plant disclosed herein is provided.

The regenerable cells in such tissue cultures may be derived, for example, from embryos, meristems, cotyledons, pollen, leaves, anthers, roots, root tips, pistil, flower, seed and stalks. Still further, the present invention provides carrot plants regenerated from a tissue culture of the invention, the plants having all the physiological and morphological characteristics of a plant provided herein.

In still yet another aspect, the invention provides a container of hybrid or non-hybrid carrot seeds where roots grown from greater than 50% of the seeds have an increased lycopene content, where a population of about 50 roots grown from the seeds contains an average lycopene content of between about 100 ppm and 250 ppm.

In another aspect, the present invention provides a container of hybrid carrots having at least a portion of the carrots with increased lycopene content, where the increased lycopene content is measured as an average lycopene content in a population of at least about 10 carrots of between about 100 ppm and about 250 ppm.

These and other features and advantages of this invention are described in, or are apparent from, the following detailed description of various exemplary embodiments of the devices and methods according to this invention.

DETAILED DESCRIPTION OF THE INVENTION

The invention provides carrot plants and in particular carrot cultivars or lines having increased lycopene content. Such carrots can be referred to as high lycopene carrot varieties. In a certain aspects, the carrot plants are hybrid carrot plants. Also disclosed herein are carrot cultivars or lines having increased lycopene content and cytoplasmic male sterility. Methods of breeding high lycopene carrot lines are also provided. Also disclosed herein are F₁ hybrids of the high lycopene carrots.

As part of this invention, long, cylindrical shaped carrots containing the carotenoid lycopene have been developed to fit market needs, including the processing needs for the cut and peel market segment. Lycopene has received much attention with regard to its anti-oxidant capability in warding off cancer development, particularly in the digestive tract. In some embodiments, the carrots provided by this invention can be used to produce a solid red colored pack of cut and peel product or mixed into a blend of red, orange and yellow carrots. Oversize carrots also provided by this invention may be used for juice production.

Any carrot plant having a suitable lycopene content can be used in conjunction with the present invention. Carrots with suitable lycopene levels can be used in the methods of the present invention. In a preferred aspect, the source of an increased lycopene content is an elite plant. In an aspect, suitable lycopene carrots may be produced by breeding with the following lycopene sources: Nutri-red, red Indian descent carrots, and Kintoki open pollinated lines. In one aspect, a lycopene source carrot can be identified by determining the lycopene level in a carrot root, for example as described below. In an aspect, a lycopene source carrot plant may be crossed with any inbred carrot line having desired properties.

The invention also provides methods and compositions relating to plants, seeds and derivatives of carrot line RN 71-4904C (previously designated 71 0302), RF 71-4911A, RF 71-4912A, RIF 71-4966C, RIF 71-4967B, or RIF 71-4968B. These lines show uniformity and stability within the limits of environmental influence for the traits described hereinafter. Each of the carrot lines RN 71-4904C, RF 71-4911A, RF 71-4912A, RIF 71-4966C, RIF 71-4967B, and RIF 71-4968B provides sufficient seed yield. By crossing with a distinct second plant, uniform F₁ hybrid progeny can be obtained.

Of the hybrid carrot varieties developed by this invention, 0710 0325, 0710 0339, and 0710 0346, exhibit a more slender and longer root shape, which, for example, makes them well suited for use in the cut and peel market segment.

In contrast other carrot varieties also developed as part of this invention, for example, carrot hybrid varieties 710313, 710305, 710316, 710319, 710311, 710304, 710310, and 710303 are heavier and broader in diameter, which, for example, makes them more applicable to the juicing market segment.

A. ORIGIN AND BREEDING HISTORY OF CARROT LINES AND HYBRID VARIETIES

1. Development of Open Pollinated Inbred Carrot Line RN 71-4904C (Previously Designated 71 0302)

High lycopene carrot line RN 71-4904C was obtained as outlined below. This carrot line is the result of a pedigree breeding system, initiated with a fertile×fertile cross between Tycopene 71B′ (a Seminis inbred line) and ‘7262B’ (a USDA carrot release containing anthocyanin and carotene). The Tycopene 71B′ is an M4 high lycopene selection from the Seminis carrot release ‘Nutri-red’.

The breeding process can be summarized as follows:

Fall Year 1 Planted parental lines in Brawley, CA (‘Lycopene 71B’ and ‘7262B’) Spring, Harvested parental roots and crossed in Fertile x Fertile Year 2 fashion. Fall Year 2 Planted Fertile x Fertile seed in California Spring Harvested vigorous F₁ roots from the F x F population and Year 3 self pollinate Fall Year 3 Planted F₂ population seed in California Spring Made F₂ selections, one being a red colored, cylindrical Year 4 shaped root. Made a 3 root small mass for F₂M population. Fall, Year 4 Planted F₂M population seed in California Spring Selected the same root form as the F₂. Again, increased to Year 5 F₂M₂ via 3 root mass population. Fall Year 5 Planted F₂M₂ population seed in California. Spring Grew out F₂M₂ population, but not harvested. No breeding Year 6 action taken. Fall Year 6 Replanted F₂M₂ population seed in California. Spring Selected for same criteria as the F₂M population. Increase Year 7 via 4 root mass to produce the F₂M₃ generation. Fall Year 7 Planted F₂M₃ population seed in California. Spring Selected for same criteria as in the F₂M₂ population. Year 8 Increase via 3 root mass to produce the F₂M₄ generation. Fall Year 8 Planted F₂M₄ population seed in California. Spring Selected for same criteria as in F₂M₃ population. Increase Year 9 via a 12 root mass for a larger seed increase. Fall Year 9 Planted F₂M₅ population seed in California. Spring, The name PSR 71 0302 was applied (subsequently changed Year 10 to RN 71-4904C) and the trial observed. Fall Year 10 Planted F₂M₆ population seed in California, as well as the new male sterile lines developed for hybridization (see breeding process Example 4, below). Spring Harvested roots of male sterile lines and pollinators. Year 11 Transplanted stecklings into hybrid cage isolations. Fall Year 11 Planted hybrid seed in California. Spring Harvested and selected the best performing hybrid Year 12 combinations.

During the breeding program, a red cylindrical shaped carrot type emerged from the F₂ population and was selected. Small mass selection for the ‘Nantes’ root shape was repeated, and dark red color expressed through the core resulted in a very stable and uniform style root. One line was selected for having a high level of uniformity from one root to the next to obtain seed quantities for presentation, using a 12 root mass and designated Red Nantes, also designated RN 71-4904C. Very little variability within the line was observed, other than that expressed by environmental influence within any field condition.

2. Development of Open Pollinated Inbred Carrot Lines

Open pollinated carrot lines are also obtained from crosses using Indian red carrot lines as one of the parents. One source of genetic diversity is from the Indian germplasm, but these sources are basically tropical or annual type carrots. This can make them less suitable for use in temperate climates. These landrace lines also tend to have defects such as early, nearly annual bolting behavior, severe forking and irregular root shapes, prolific root hair growth, extreme variability in root type, shape, lycopene content, or any other phenotypic characteristic.

These Indian lines contain several advantages however, such as: 1) ability to accumulate moderate levels of lycopene and 2) extreme genetic diversity, including excellent eating quality. This eating quality can be the result of high juice content and low terpenoid levels.

Thus, to develop other high lycopene plant material, the following breeding strategy may be used:

-   -   a) Indian descent (red) crossed with Lycopene 71B (red) (see         above).     -   b) Indian descent (red) crossed with cut and peel material         (orange) (S-D813B, see U.S. Pat. No. 6,787,685).     -   c) Nutri-red (red) crossed with cut and peel material (orange)         (S-D813B, see U.S. Pat. No. 6,787,685).

For example, the following scheme was used:

Fall, Year 1 Planted parental lines in Brawley, CA (‘Lycopene 71B’, Indian germplasm, and S-D813B). Spring Harvested parental roots and cross in Fertile x Fertile Year 2 fashion. Fall, Year 2 Planted Fertile x Fertile seed in California Spring Harvested vigorous F₁ roots from the F x F population and Year 3 sib-mate for the F₁M populations (simulated F₂). Fall, Year 3 Planted F₁M population seed in California Spring Made F₁M selections, selecting for cut and peel style or any Year 4 full, interesting carrot shapes of normal behavior and expressing red color. Observations indicated vast differences from the original Indian material, which is severely early in bolting (almost annual in behavior), tends to have multiple branched (forked) roots and prolific root hair growth. September Planted F₁M₂ population seed in California Fall, Year 4 Spring Selected the same root form as the F₁M; increased to F₁M₃ Year 5 via 2 or 3 root mass populations. Fall, Year 5 Planted F₁M₃ population seed in California. Spring Selected for same criteria as the F₁M₂ population. Increased Year 6 via 2 or 3 root mass to produce the F₁M₄ generation. September Planted F₁M₄ population seed in California. Fall, Year 6 Spring Evaluated lines for possible use as parents. Chose most Year 7 promising lines for hybrid development and parental increase. Fall, Year 7 Planted new hybrids and parentals for advancement and seed increase.

3. Development of Cytoplasmic Male-Sterile Carrot Lines

Carrot lines containing cytoplasmic male sterility having increased lycopene content can be produced, for example, using crosses between open-pollinated Nutri-red lines and an orange male sterile variety to introduce the cytoplasmic male sterility into the high lycopene background.

For example, below is a breeding process that has been used for the development of male sterile, high lycopene lines:

Fall, Year 1 Planted Nutri-red (red) and Orange male sterile seed in Imperial Valley. Spring, Year 2 Harvested roots of Nutri-red and orange male sterile lines for F₁ hybrids. Fall, Year 2 Planted hybrid seed in California. Spring, Year 3 Harvested hybrids of Nutri-red and Orange roots (all orange) in preparation of first backcross. Fall, Year 3 Planted BC₁ seed in California. Spring, Year 4 Selected red roots within the BC₁ population and prepared for backcrossing to Nutri-red. Fall, Year 4 Planted BC₂ seed in California Spring, Year 5 Most backcrosses appeared to be nearly stable, though some orange roots were observed. Red roots were again selected and prepared for backcrossing to Nutri-red. Fall, Year 5 Planted BC₃ seed in California. Spring, Year 6 Harvested roots, 100% of all backcross populations have complete expression of increased lycopene phenotype. Selected best lines for hybrid production and possible increase. Fall, Year 6 Planted new hybrids and backcrossed lines for advancement and seed increase.

Following the above program, carrot lines having increased lycopene content were been obtained, which also exhibited cytoplasmic male sterility.

4. Development of Hybrid Carrot Varieties Having High Lycopene Content

Hybrid carrots have been developed by crossing the open pollinators of Example 2 and 3 (male parents) with the male-sterile lines of Example 4 (female parents), and collecting the hybrid F₁ seeds. Several hybrid varieties have been developed that contain increased levels of lycopene. These are identified as hybrid varieties 710303, 710304, 710310, 710313, 710311, 710319, 710316, and 710305. After harvesting roots from the hybrid varieties, it was observed that hybrid line 710319 segregates for orange and red, and as such did not result in a high lycopene carrot. These hybrids comprise an average lycopene content in their roots of at least 115 ppm, as determined by HPLC.

C. BREEDING ADDITIONAL CARROT LINES

One aspect of the current invention concerns methods for crossing the carrot line RN 71-4904C, RF 71-4911A, RF 71-4912A, RIF 71-4966C, RIF 71-4967B, or RIF 71-4968B with itself or a second plant and the seeds and plants produced by such methods. These methods can be used for propagation of line RN 71-4904C, RF 71-4911A, RF 71-4912A, RIF 71-4966C, RIF 71-4967B, or RIF 71-4968B, or can be used to produce hybrid carrot seeds and the plants grown therefrom. Hybrid seeds are produced by crossing line RN 71-4904C, RF 71-4911A, RF 71-4912A, RIF 71-4966C, RIF 71-4967B, or RIF 71-4968B with second carrot parent line.

The development of new varieties using one or more starting varieties is well known in the art. In accordance with the invention, novel varieties may be created by crossing line RN 71-4904C, RF 71-4911A, RF 71-4912A, RIF 71-4966C, RIF 71-4967B, or RIF 71-4968B followed by multiple generations of breeding according to such well known methods. New varieties may be created by crossing with any second plant. In selecting such a second plant to cross for the purpose of developing novel lines, it may be desired to choose those plants which either themselves exhibit one or more selected desirable characteristics or which exhibit the desired characteristic(s) in progeny. Once initial crosses have been made, inbreeding and selection take place to produce new varieties. For development of a uniform line or population, often five or more generations of selfing or sib-mating and selection are involved.

Backcrossing can also be used to improve a line. Backcrossing transfers a specific desirable trait from one line to a line lacks that trait. This can be accomplished, for example, by first crossing a superior plant (A) (recurrent parent) to a donor plant (non-recurrent parent), which carries the appropriate locus or loci for the trait in question. The progeny of this cross are then mated back to the superior recurrent parent (A) followed by selection in the resultant progeny for the desired trait to be transferred from the non-recurrent parent. After five or more backcross generations with selection for the desired trait, the progeny are heterozygous for loci controlling the characteristic being transferred, but are like the superior parent for most or almost all other loci. The last backcross generation would be selfed to give pure breeding progeny for the trait being transferred.

The line of the present invention is particularly well suited for the development of new lines based on the elite nature of the genetic background of the line. In selecting a second plant to cross with RN 71-4904C, RF 71-4911A, RF 71-4912A, RIF 71-4966C, RIF 71-4967B, or RIF 71-4968B for the purpose of developing novel carrot lines, it will typically be preferred to choose those plants which either themselves exhibit one or more selected desirable characteristics or which exhibit the desired characteristic(s) when in hybrid combination. Examples of desirable characteristics may include, but are not limited to, desirable root characteristics, such as color, diameter, length, uniform taper, minimal forking, high moisture, soluble solids content, crispness, and sweetness. Additional examples of desirable characteristics may include disease tolerance, insect resistance, adaptability for soil conditions, adaptability for climate conditions, germination, seedling vigor, growth rate, maturity, plant uniformity, increased phytochemical content, increased beta-carotene content, increased xanthophyll content, increased lycopene content, and increased anthocyanin content.

As used herein, an “elite line” is any line that has resulted from breeding and selection for superior agronomic performance. An elite plant is any plant from an elite line. Examples of elite lines are lines that are commercially available to farmers or carrot breeders such as A-Plus, HCM, B8080, B6274, B5280, B6333, B5238, and B6274 (each available from the USDA).

Plants that have been self pollinated once or twice followed by sib pollination and selected for type over many generations retain some genotypic heterozygosity, but become phenotypically uniform. Such a breeding procedure is used with carrots which suffer significant inbreeding depression. A cross between two such heterozygous but homogeneous parents produces a phenotypically uniform population of hybrid plants that are heterozygous for many gene loci. The development of such parent lines generally requires at least about 5 to 7 generations of selfing and/or sib mating. Two such parent lines can then be crossed to develop improved F₁ hybrids. Hybrids can then be screened and evaluated in small scale field trials. Typically, about 10 to 15 phenotypic traits, selected for their potential commercial value, can be measured. In another aspect, dihaploid plants are developed and these plants are genotypically uniform. Two such plants can be crossed, or a conventionally produced parent line described above can be crossed with a dihaploid, producing F₁ hybrids that are evaluated as described above.

The present invention also provides progeny of high lycopene carrots. As used herein, the progeny include not only, without limitation, the products of any cross (be it a backcross or otherwise) between two plants, but all progeny whose pedigree traces back to the original cross. Specifically, without limitation, such progeny include plants that have 50%, 25%, 12.5% or less genetic material derived from one of the two originally crossed plants. As used herein, a second plant is derived from a first plant if the second plant's pedigree includes the first plant.

Plants generated using a method of the present invention can be part of or generated from a breeding program. The choice of breeding method depends on the mode of plant reproduction, the heritability of the trait(s) being improved, and the type of cultivar used commercially (e.g., F₁ hybrid cultivar, pureline cultivar, etc). Selected, non-limiting approaches, for breeding the plants of the present invention are set forth below. A breeding program can be enhanced using any method available, such as, marker assisted selection of the progeny of any cross. It is further understood that any commercial and non-commercial cultivars can be utilized in a breeding program. Factors such as, for example, emergence vigor, vegetative vigor, stress tolerance, disease resistance, branching, flowering, seed set, seed size, seed density, standability, and threshability etc. will generally dictate the choice.

The present invention provides processes of preparing novel carrot plants and carrot plants produced by such processes. In accordance with such a process, a first parent carrot plant may be crossed with a second parent carrot plant wherein at least one of the first and second carrot plants is a parent line or dihaploid line or open pollinated line high lycopene carrot plant as described herein. One application of the process is in the production of F₁ hybrid plants. Another important aspect of this process is that the process can be used for the development of novel parent, dihaploid or open pollinated lines. For example, a high lycopene carrot plant as described herein could be crossed to any second plant, and the resulting hybrid progeny each selfed and/or sibbed for about 5 to 7 or more generations, thereby providing a large number of distinct, parent lines. These parent lines could then be crossed with other lines and the resulting hybrid progeny analyzed for beneficial characteristics. In this way, novel lines conferring desirable characteristics could be identified.

Carrot plants (Daucus carota var. sativus) can be crossed by either natural or mechanical techniques. Mechanical pollination can be effected either by controlling the types of pollen that can be transferred onto the stigma or by pollinating by hand.

In another aspect, the present invention provides a method of producing a carrot plant having an increased lycopene content comprising: (a) crossing a carrot line having increased lycopene with a second carrot line to form a segregating population; (b) screening the population for increased lycopene content; and (c) selecting one or more members of the population having increased lycopene content.

In another aspect, the present invention provides a method of introgressing a high lycopene content trait into a carrot plant comprising: (a) crossing at least a first carrot line having an increased lycopene content with a second carrot line to form a segregating population; (b) screening the population for lycopene content; and (c) selecting at least one member of the population having an increased lycopene content.

Parental plants are typically planted in pollinating proximity to each other by planting the parental plants in alternating rows, in blocks or in any other convenient planting pattern. Where the parental plants differ in timing of sexual maturity, it may be desired to plant the slower maturing plant first, thereby ensuring the availability of pollen from the male parent during the time at which the stigmas on the female parent are receptive to pollen. Plants of both parental parents are cultivated and allowed to grow until the time of flowering. Advantageously, during this growth stage, plants are in general treated with fertilizer and/or other agricultural chemicals as considered appropriate by the grower.

Alternatively, in another aspect of the invention, both first and second parent carrot plants can be a high lycopene carrot plant as described herein. Thus, any carrot plant produced using a high lycopene carrot plant as described herein forms a part of the invention. As used herein, crossing can mean selfing, backcrossing, crossing to another or the same parent line, crossing to populations, and the like. All carrot plants produced using a high lycopene carrot plant as described herein as a parent are, therefore, within the scope of this invention.

In one aspect, any male carrot can be used in combination with carrots of the present invention. In one aspect, one of the parents is a male carrot having a root with a lycopene content of at least 50 ppm, 55 ppm, 60 ppm, 65 ppm, 70 ppm, 75 ppm, 80 ppm, 85 ppm, 90 ppm, 95 ppm, or 100 ppm. Examples of such male carrot lines include Nutri-red, and lines of red Indian descent carrots.

In another aspect, the present invention provides a hybrid carrot plant having an increased lycopene content. In another aspect, the present invention provides seed of a hybrid carrot plant having an increased lycopene content. Any time a high lycopene carrot plant as described herein is crossed with another, different, carrot parent line, a first generation (F₁) carrot hybrid plant is produced. As such, an F₁ hybrid carrot plant can be produced by crossing a high lycopene carrot plant, for example, as described herein with any second parent carrot plant. Essentially any other carrot plant can be used to produce a hybrid carrot plant having a high lycopene carrot plant as described herein as one parent. All that is required is that, at a minimum, one plant be female fertile and the second plant be male fertile. Carrot plants naturally are both male and female fertile.

A single cross hybrid carrot variety is the cross of two parent lines, each of which has a genotype which complements the genotype of the other. Typically, F₁ hybrids are more vigorous than their parents. This hybrid vigor, or heterosis, is manifested in many polygenic traits, including improved yields, better roots, better uniformity and better insect and disease resistance. In the development of hybrids only the F₁ hybrid plants are typically sought. An F₁ single cross hybrid is produced when two parent plants are crossed. A double cross hybrid is produced from four parent plants crossed in pairs (A×B and C×D) and then the two F₁ hybrids are crossed again (A×B)×(C×D). A three-way cross is produced from three parent plants crossed as (A×B)×C.

In one aspect, any of the carrot varieties known to those of skill in the art can be crossed with a high lycopene carrot line of the present invention to produce a hybrid plant. In a preferred aspect, such carrot varieties include, but are not limited to B3640M, B3080M, B3475, B8080, B5280, B6333, B5238, and B6274 (each available from the USDA)S-D813B (Seminis Vegetable Seeds, and U.S. Pat. No. 6,787,685, the entirety of which is incorporated herein by reference).

When a high lycopene carrot plant as described herein is crossed with another parent plant to yield a hybrid, it can serve as either the maternal or paternal plant. For many crosses, the outcome is the same regardless of the assigned sex of the parental plants. Depending on the seed production characteristics relative to a second parent in a hybrid cross, it may be desired to use one of the parental plants as the male or female parent. Therefore, a decision to use one parent plant as a male or female may be made based on any such characteristics as is well known to those of skill in the art.

The development of new varieties using one or more starting varieties is well known in the art. In accordance with the invention, novel varieties may be created by crossing a high lycopene carrot plant as described herein followed by multiple generations of breeding according to such well known methods. New varieties may be created by crossing a high lycopene carrot plant as described herein with any second plant. In selecting such a second plant to cross for the purpose of developing novel parent lines, it may be desired to choose those plants which either themselves exhibit one or more selected desirable characteristics or which exhibit the desired characteristic(s) when in hybrid combination. Examples of potentially desired characteristics include greater yield, resistance to insecticides, herbicides, pests, and disease, tolerance to heat and drought, reduced time to crop maturity, better agronomic quality, higher nutritional value, and uniformity in germination times, growth rate, maturity, and root size.

Once initial crosses have been made with a high lycopene carrot line of the present invention, selfing and/or sibbing take place to produce new parent lines. The development of parent lines requires manipulation by human breeders. A combination of self pollination and sib pollination is essential to develop a new parent line that is genotypically stable and phenotypically uniform. The reason for the breeder to create parent lines is to develop homogeneous populations in an outcrossing species that are phenotypically uniform and can be utilized to produce F₁ hybrids.

The pedigree breeding method involves crossing two genotypes. Each genotype can have one or more desirable characteristics lacking in the other; or, each genotype can complement the other. If the two original parental genotypes do not provide all of the desired characteristics, other genotypes can be included in the breeding population. Superior plants that are the products of these crosses are selfed or sibbed and selected in successive generations. Each succeeding generation becomes more genetically homogeneous and phenotypically uniform as a result of self- or sib-pollination and selection. Typically, this method of breeding involves five or more generations of selfing or sibbing and selection. After at least five generations, the resulting parent line has a stable allelic frequency at each locus and is phenotypically uniform.

Many traits have been identified that are not regularly selected for in the development of a new variety but that can be improved by backcrossing techniques. A genetic locus conferring the traits may or may not be transgenic. Examples of such traits known to those of skill in the art include, but are not limited to, male sterility, herbicide resistance, resistance for bacterial, fungal, or viral disease, insect resistance, male fertility and enhanced nutritional quality. These genes are generally inherited through the nucleus, but may be inherited through the cytoplasm. Some known exceptions to this are genes for male sterility, some of which are inherited cytoplasmically, but still act as a single locus trait.

Direct selection may be applied where a genetic locus acts as a dominant trait. An example of a dominant trait is the herbicide resistance trait. For this selection process, the progeny of the initial cross are sprayed with the herbicide prior to the backcrossing. The spraying eliminates any plants which do not have the desired herbicide resistance characteristic, and only those plants which have the herbicide resistance gene are used in the subsequent backcross. This process is then repeated for all additional backcross generations.

E. FURTHER EMBODIMENTS OF THE INVENTION

When the term carrot line RN 71-4904C, RF 71-4911A, RF 71-4912A, RIF 71-4966C, RIF 71-4967B, or RIF 71-4968B is used in the context of the present invention, this also includes plants modified to include at least a first desired heritable trait. Such plants may, in one embodiment, be developed by a plant breeding technique called backcrossing, wherein essentially all of the desired morphological and physiological characteristics of a variety are recovered in addition to a genetic locus transferred into the plant via the backcrossing technique. The term single locus converted plant as used herein refers to those carrot plants which are developed by a plant breeding technique called backcrossing, wherein essentially all of the desired morphological and physiological characteristics of a variety are recovered in addition to the single locus transferred into the variety via the backcrossing technique.

Backcrossing methods can be used with the present invention to improve or introduce a characteristic into the present variety. The parental carrot plant which contributes the locus for the desired characteristic is termed the nonrecurrent or donor parent. This terminology refers to the fact that the nonrecurrent parent is used one time in the backcross protocol and therefore does not recur. The parental carrot plant to which the locus or loci from the nonrecurrent parent are transferred is known as the recurrent parent as it is used for several rounds in the backcrossing protocol.

In a typical backcross protocol, the original variety of interest (recurrent parent) is crossed to a second variety (nonrecurrent parent) that carries the single locus of interest to be transferred. The resulting progeny from this cross are then crossed again to the recurrent parent and the process is repeated until a carrot plant is obtained wherein essentially all of the desired morphological and physiological characteristics of the recurrent parent are recovered in the converted plant, in addition to the single transferred locus from the nonrecurrent parent.

The selection of a suitable recurrent parent is an important step for a successful backcrossing procedure. The goal of a backcross protocol is to alter or substitute a single trait or characteristic in the original variety. To accomplish this, a single locus of the recurrent variety is modified or substituted with the desired locus from the nonrecurrent parent, while retaining essentially all of the rest of the desired genetic, and therefore the desired physiological and morphological constitution of the original variety. The choice of the particular nonrecurrent parent will depend on the purpose of the backcross; one of the major purposes is to add some commercially desirable trait to the plant. The exact backcrossing protocol will depend on the characteristic or trait being altered to determine an appropriate testing protocol. Although backcrossing methods are simplified when the characteristic being transferred is a dominant allele, a recessive allele may also be transferred. In this instance it may be necessary to introduce a test of the progeny to determine if the desired characteristic has been successfully transferred.

In one embodiment, progeny carrot plants of a backcross in which RN 71-4904C, RF 71-4911A, RF 71-4912A, RIF 71-4966C, RIF 71-4967B, or RIF 71-4968B is the recurrent parent comprise (i) the desired trait from the non-recurrent parent and (ii) all of the physiological and morphological characteristics of carrot line RN 71-4904C, RF 71-4911A, RF 71-4912A, RIF 71-4966C, RIF 71-4967B, or RIF 71-4968B as determined at the 5% significance level when grown in the same environmental conditions.

Carrot varieties can also be developed from more than two parents. The technique, known as modified backcrossing, uses different recurrent parents during the backcrossing. Modified backcrossing may be used to replace the original recurrent parent with a variety having certain more desirable characteristics or multiple parents may be used to obtain different desirable characteristics from each.

Many single locus traits have been identified that are not regularly selected for in the development of a new line but that can be improved by backcrossing techniques. Single locus traits may or may not be transgenic; examples of these traits include, but are not limited to, male sterility, herbicide resistance, resistance to bacterial, fungal, or viral disease, insect resistance, restoration of male fertility, modified fatty acid or carbohydrate metabolism, and enhanced nutritional quality. These comprise genes generally inherited through the nucleus.

Direct selection may be applied where the single locus acts as a dominant trait. An example of a dominant trait is the anthracnose resistance trait. For this selection process, the progeny of the initial cross are sprayed with anthracnose spores prior to the backcrossing. The spraying eliminates any plants which do not have the desired anthracnose resistance characteristic, and only those plants which have the anthracnose resistance gene are used in the subsequent backcross. This process is then repeated for all additional backcross generations.

Selection of carrot plants for breeding is not necessarily dependent on the phenotype of a plant and instead can be based on genetic investigations. For example, one can utilize a suitable genetic marker which is closely genetically linked to a trait of interest. One of these markers can be used to identify the presence or absence of a trait in the offspring of a particular cross, and can be used in selection of progeny for continued breeding. This technique is commonly referred to as marker assisted selection. Any other type of genetic marker or other assay which is able to identify the relative presence or absence of a trait of interest in a plant can also be useful for breeding purposes. Procedures for marker assisted selection applicable to the breeding of carrot are well known in the art. Such methods will be of particular utility in the case of recessive traits and variable phenotypes, or where conventional assays may be more expensive, time consuming or otherwise disadvantageous. Types of genetic markers which could be used in accordance with the invention include, but are not necessarily limited to, Simple Sequence Length Polymorphisms (SSLPs) (Williams et al., 1990), Randomly Amplified Polymorphic DNAs (RAPDs), DNA Amplification Fingerprinting (DAF), Sequence Characterized Amplified Regions (SCARs), Arbitrary Primed Polymerase Chain Reaction (AP-PCR), Amplified Fragment Length Polymorphisms (AFLPs) (EP 534 858, specifically incorporated herein by reference in its entirety), and Single Nucleotide Polymorphisms (SNPs) (Wang et al., 1998).

The present application provides for carrot lines having high lycopene levels. In a preferred aspect, the carrot lines are hybrid carrot varieties. In another aspect, the present invention provides a carrot root having an increased lycopene content. Lycopene content of any of the carrot roots provided herein can be measured by any means available in the art. In one example, lycopene content of carrot roots is determined using high pressure liquid chromatography (HPLC) as described in Example 1 below. In one example, the carrot root as provided herein has a lycopene content of at least, or about 100 parts per million (ppm), 105 ppm, 110 ppm, 115 ppm, 120 ppm, 125 ppm, 130 ppm, or 135 ppm. In a preferred aspect, the carrot roots have an average lycopene content of at least about 100 ppm, 105 ppm, 110 ppm, 115 ppm, 120 ppm, 125 ppm, 130 ppm, 135 ppm, 140 ppm, 145 ppm, or 150 ppm. In another aspect, the carrot roots have an average lycopene content of between about 100 ppm and about 250 ppm, about 100 ppm and about 225 ppm, about 100 ppm and about 200 ppm, about 100 ppm and about 175 ppm, about 100 ppm and about 160 ppm, or about 100 ppm and about 150 ppm.

In another aspect, carrot lines having high lycopene content have a lycopene content that is increased at least, or greater than, 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, or 30% relative to a control carrot line. In one embodiment, the control carrot line is Nutri-red. Nutri-red is well known variety to those of skill in the art. In specific embodiments the lycopene content of the roots of a plant provided herein may therefore be defined as comprising at least about 110% of the average root lycopene content of Nutri-red when grown under the same conditions. In further embodiments the root lycopene content may be defined as at least about 115, 120, 125, 130, 132.5, 135, 138.8, 145.4, 148.7, 152.1, 157.9, or about 171.1% of the lycopene content of Nutri-red when grown under the same conditions.

Average lycopene content of high lycopene carrot lines, as provided herein, can be determined by averaging the lycopene content of any number of roots from a line or cultivar. In one example, average lycopene content is the average of about 2, 5, 10, 15, 20, 25, 30, 35, 40, 45, or 50 roots. In a preferred aspect, the carrot plant from which the root is obtained is a male sterile plant. In another preferred aspect, the carrot plant from which the root is obtained is a cytoplasmic male sterile plant.

In another aspect, the present invention provides seed of a carrot plant capable of producing a plant having roots with a lycopene content of at least 100 ppm. In a preferred aspect, the carrot plant is grown from the seed is a male sterile plant. In another preferred aspect, the male sterile plant is a cytoplasmic male sterile plant.

The present invention also provides a cytoplasmic male sterile carrot plant having a root with an increased lycopene content.

The present invention also provides a hybrid carrot variety having a root comprising an increased lycopene content. In one example, the carrot root has an increased lycopene content of at least about 80 ppm, 85 ppm, 90 ppm, 95 ppm, 100 ppm, 105 ppm, 110 ppm, 115 ppm, 120 ppm, 125 ppm, 130 ppm, or 135 ppm. In a preferred aspect, the carrot roots have an average lycopene content of at least about 80 ppm, 85 ppm, 90 ppm, 95 ppm, 100 ppm, 105 ppm, 110 ppm, 115 ppm, 120 ppm, 125 ppm, 130 ppm, 135 ppm, 140 ppm, 145 ppm, or 150 ppm. In another aspect, the carrot roots have an average lycopene content of between about 80 ppm and about 250 ppm, about 80 ppm and about 225 ppm, about 90 ppm and about 225 ppm, about 100 ppm and about 225 ppm, about 100 ppm and about 200 ppm, about 100 ppm and about 175 ppm, or about 100 ppm and about 160 ppm, or about 100 ppm and about 150 ppm. In one embodiment, the lycopene content is measured as an average lycopene content of at least about 2, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50 carrot roots obtained from the hybrid carrot variety. In another aspect, the hybrid carrot varieties have an increased lycopene content compared to an average lycopene content obtained from a control hybrid carrot variety, for example a Kintoki open pollinated variety. For example, a carrot root obtained from a hybrid carrot of the present invention has an average lycopene content that is increased at least, or greater than, about 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, or 30% compared to a root obtained from a control carrot line.

In another aspect, the present invention provides a carrot having a root having a color corresponding to a color in the 184 color group on the Royal Horticultural Society Color Chart (Royal Horticultural Society Publications, London, UK). In a preferred aspect, the root has a color in the 184 color group between colors RHS 184 A and RHS 184C. In a preferred aspect, the root has a color between RHS 184A and RHS 184B. In one aspect, the root has a color between RHS 184A and RHS 184C to a depth below the root surface of about, or at least 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 millimeters (mm). The depth of color is measured by measuring the color of the root from the surface to the deepest point of color.

In another aspect, the present invention provides a high lycopene carrot plant having commercially desirable root quality traits, such as crispness and sweetness, while minimizing other traits, such as forking. A review of these traits is found in “Domestication, Historical Development, and Modern Breeding of Carrot,” P. W. Simon, Plant Breeding Reviews, 19:157-190 (ed. J. Janick; John Wiley & Sons 2000). “Crispness” of carrot roots is defined as the fracture of the root after applying a given force. “Sweetness” is the result of a carrot root's sugar content, which can, for example, be measured as soluble solids by refractometer, and expressed as degrees brix. In one aspect, a carrot plant of the present invention produces a root having a brix content of about or greater than 4°, 5°, 6°, 7°, 8°, 9°, 10°, 11°, 12°, 13°, 14°, 15°, 16°, 17°, 18° brix. In another aspect, a carrot plant of the present invention produces a root having between about 2° and about 20° brix, between about 3° and about 20° brix, between about 8° and about 20° brix, or between about 11° brix and about 20° brix.

“Forking” can occur when carrots are grown in hard clay soil, are grown in rocky soil, or are grown in crowded conditions, or due to excessive nitrogen presence, or due to various pathogens, and results in growth of secondary roots from the primary tap root. In one aspect, a population of roots of carrot lines of the present invention have less than 25%, 20%, 15%, 10%, 5% forking. Crispness, forking, and sweetness can be measured by any method known in the art. For example, crispness, sweetness, and forking may be measured by comparison of a test root to a reference standard carrot root grown under similar conditions.

In an aspect, a carrot of the present invention has a root having a diameter at harvest of about or greater than 12 millimeters (mm), 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm, 21 mm, 22 mm, 23 mm, 24 mm, 25 mm, 26 mm, 27 mm, 28 mm, 29 mm, 30 mm, 31 mm, 32 mm, 33 mm, 34 mm, 35 mm, 36 mm, 37 mm, 38 mm, 39 mm, 40 mm, 41 mm, 42 mm, 43 mm, 44 mm, 45 mm, 46 mm, 47 mm, 48 mm, 49 mm, 50 mm, or 51 mm. In another aspect, a carrot has a root having a diameter at harvest between about 10 mm and about 55 mm, between about 12 mm and about 53 mm, between about 15 mm and about 50 mm, or between about 17 mm and about 48 mm. As used herein, root diameter at harvest is measured by measuring the diameter of the root at its widest point.

In an aspect, a carrot of the present invention has a root length at harvest of about or greater than 7.5 centimeters (cm), 8.0 cm, 8.5 cm, 9.0 cm, 9.5 cm, 10.0 cm, 10.5 cm, 11.0 cm, 11.5 cm, 12.0 cm, 12.5 cm, 13.0 cm, 13.5 cm, 14.0 cm, 14.5 cm, 15.0 cm, 20 cm, 25 cm, 30 cm, 35 cm, or 40 cm. In another aspect, a carrot of the present invention has a root length at harvest between about 5 cm and about 40 cm, between about 7.5 cm and about 35 cm, or between about 9 cm and about 30 cm. Root length is measured at the longest point of the root from top to bottom in centimeters. As used herein, root length is measured by measuring the harvest root along the length of the root between the greatest points.

In an aspect, a carrot root has an overall root quality rating of 1, 2, 3, 4, or 5, where root quality is measured by visual inspection, with a scale ranging from 1=poor through 5=excellent.

A carrot attribute such as color, root length, and root lycopene content can be measured at a variety of times. In another aspect, an attribute is measured following growth in a growth chamber. In one aspect, an attribute is measured at the time of harvest. In another aspect, an attribute is measured after storage of the carrot root at ambient conditions for one day, two days, three days, four days, five days, six days, one week, two weeks, three weeks, four weeks, or five weeks after harvest. In yet another aspect, an attribute is measured after storage of the carrot root at 5° C. for one day, two days, three days, four days, five days, six days, one week, two weeks, three weeks, four weeks, or five weeks.

As used herein, a carrot plant exhibits “favorable root characteristics” if the root has a diameter of between about 20 to about 50 millimeters (mm) and a length between about 50 to about 500 mm, and has a minimal amount of forking and a minimal core. In one aspect, a carrot plant demonstrates less than 25%, 20%, 15%, 10%, or 5% of its carrots having forked roots. In another aspect, a carrot root demonstrates a cortex diameter that is less than 60%, 55%, 50%, 45%, or 40% of the diameter of the total diameter of the root. In another aspect, a carrot root that has a discernable “sweetness” refers to the sensory perception of sweetness of the carrot root. In one aspect, sweetness can be correlated to the content of soluble solids in the carrot root. Soluble solids of a root can be measured as degrees brix by refractometry, and preferably is at least 4°, 6°, 8°, 10°, 12°, 14°, 16°, 18°, 20° brix or greater. Sweetness can also be affected by the amount of terpenoids, such as Pike or Simon terpenes, produced in the carrot root. Terpene content can be measured using any method available in the art, for example, using HPLC. Preferably, the root contains less than 50 ppm, 45 ppm, 40 ppm, 35 ppm, 30 ppm of terpenoids.

A further aspect of the invention relates to tissue cultures of the carrot lines described herein. As used herein, the term “tissue culture” indicates a composition comprising isolated cells of the same or a different type or a collection of such cells organized into parts of a plant. Exemplary types of tissue cultures are protoplasts, calli, anther cultures, and plant cells that are intact in plants or parts of plants, such as embryo, leaf, peduncle, pedicel, anther, meristem, tip and segments of root, stump and stem, explants, and the like. In a preferred aspect, the tissue culture comprises embryos, protoplasts, meristematic cells, pollen, leaves or anthers derived from immature tissues of these plant parts. In another preferred aspect, tissue cultures can be used in dihaploid production. Means for preparing and maintaining plant tissue cultures are well known in the art. Examples of processes of tissue culturing and regeneration of carrot are described in, for example, Matthysse et al. (1978).

High lycopene carrot lines have an average lycopene content in a population of carrot roots of the present invention that is higher than previously described carrot plants, for example, carrot lines Indian Red and Nutri-red. A population of carrot roots refers to two or more roots obtained from different carrot plants within the same carrot line, preferably 2, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 100, 200, 500, or 1000 or more roots, obtained from different carrot plants within the same carrot line, grown under similar conditions. In one aspect, average lycopene content is identified as an average lycopene content between about 100 ppm and about 250 ppm, between about 100 ppm and about 225 ppm, between about 100 ppm and about 200 ppm, between about 100 ppm and about 175 ppm, between about 100 ppm and about 165 ppm, or between about 100 ppm and about 155 ppm.

F. CARROT PLANTS DERIVED BY GENETIC ENGINEERING

Many useful traits that can be introduced by backcrossing, as well as directly into a plant, are those which are introduced by genetic transformation techniques. Genetic transformation may therefore be used to insert a selected transgene into the carrot line of the invention or may, alternatively, be used for the preparation of transgenes which can be introduced by backcrossing. Methods for the transformation of plants, including carrot, are well known to those of skill in the art. Techniques which may be employed for the genetic transformation of carrot include, but are not limited to, electroporation, microprojectile bombardment, Agrobacterium-mediated transformation and direct DNA uptake by protoplasts.

To effect transformation by electroporation, one may employ either friable tissues, such as a suspension culture of cells or embryogenic callus or alternatively one may transform immature embryos or other organized tissue directly. In this technique, one would partially degrade the cell walls of the chosen cells by exposing them to pectin-degrading enzymes (pectolyases) or mechanically wound tissues in a controlled manner.

A particularly efficient method for delivering transforming DNA segments to plant cells is microprojectile bombardment. In this method, particles are coated with nucleic acids and delivered into cells by a propelling force. Exemplary particles include those comprised of tungsten, platinum, and preferably, gold. For the bombardment, cells in suspension are concentrated on filters or solid culture medium. Alternatively, immature embryos or other target cells may be arranged on solid culture medium. The cells to be bombarded are positioned at an appropriate distance below the macroprojectile stopping plate.

An illustrative embodiment of a method for delivering DNA into plant cells by acceleration is the Biolistics Particle Delivery System, which can be used to propel particles coated with DNA or cells through a screen, such as a stainless steel or NYTEX screen, onto a surface covered with target carrot cells. The screen disperses the particles so that they are not delivered to the recipient cells in large aggregates. It is believed that a screen intervening between the projectile apparatus and the cells to be bombarded reduces the size of projectiles aggregate and may contribute to a higher frequency of transformation by reducing the damage inflicted on the recipient cells by projectiles that are too large.

Microprojectile bombardment techniques are widely applicable, and may be used to transform virtually any plant species.

Agrobacterium-mediated transfer is another widely applicable system for introducing gene loci into plant cells. An advantage of the technique is that DNA can be introduced into whole plant tissues, thereby bypassing the need for regeneration of an intact plant from a protoplast. Modern Agrobacterium transformation vectors are capable of replication in E. coli as well as Agrobacterium, allowing for convenient manipulations (Klee et al., 1985). Moreover, recent technological advances in vectors for Agrobacterium-mediated gene transfer have improved the arrangement of genes and restriction sites in the vectors to facilitate the construction of vectors capable of expressing various polypeptide coding genes. The vectors described have convenient multi-linker regions flanked by a promoter and a polyadenylation site for direct expression of inserted polypeptide coding genes. Additionally, Agrobacterium containing both armed and disarmed Ti genes can be used for transformation.

In those plant strains where Agrobacterium-mediated transformation is efficient, it is the method of choice because of the facile and defined nature of the gene locus transfer. The use of Agrobacterium-mediated plant integrating vectors to introduce DNA into plant cells is well known in the art (Fraley et al., 1985; U.S. Pat. No. 5,563,055).

Transformation of plant protoplasts also can be achieved using methods based on calcium phosphate precipitation, polyethylene glycol treatment, electroporation, and combinations of these treatments (see, e.g., Potrykus et al., 1985; Omirulleh et al., 1993; Fromm et al., 1986; Uchimiya et al., 1986; Marcotte et al., 1988). Transformation of plants and expression of foreign genetic elements is exemplified in Choi et al. (1994) and Ellul et al. (2003).

A number of promoters have utility for plant gene expression for any gene of interest including but not limited to selectable markers, scoreable markers, genes for pest tolerance, disease resistance, nutritional enhancements and any other gene of agronomic interest. Examples of constitutive promoters useful for carrot plant gene expression include, but are not limited to, the cauliflower mosaic virus (CaMV) P-35S promoter, which confers constitutive, high-level expression in most plant tissues (see, e.g., Odell et al., 1985), including monocots (see, e.g., Dekeyser et al., 1990; Terada and Shimamoto, 1990); a tandemly duplicated version of the CaMV 35S promoter, the enhanced 35S promoter (P-e35S) the nopaline synthase promoter (An et al., 1988), the octopine synthase promoter (Fromm et al., 1989); and the figwort mosaic virus (P-FMV) promoter as described in U.S. Pat. No. 5,378,619 and an enhanced version of the FMV promoter (P-eFMV) where the promoter sequence of P-FMV is duplicated in tandem, the cauliflower mosaic virus 19S promoter, a sugarcane bacilliform virus promoter, a commelina yellow mottle virus promoter, and other plant DNA virus promoters known to express in plant cells.

A variety of plant gene promoters that are regulated in response to environmental, hormonal, chemical, and/or developmental signals can be used for expression of an operably linked gene in plant cells, including promoters regulated by (1) heat (Callis et al., 1988), (2) light (e.g., pea rbcS-3A promoter, Kuhlemeier et al., 1989; maize rbcS promoter, Schaffner and Sheen, 1991; or chlorophyll a/b-binding protein promoter, Simpson et al., 1985), (3) hormones, such as abscisic acid (Marcotte et al., 1989), (4) wounding (e.g., wunl, Siebertz et al., 1989); or (5) chemicals such as methyl jasmonate, salicylic acid, or Safener. It may also be advantageous to employ organ-specific promoters (e.g., Roshal et al., 1987; Schernthaner et al., 1988; Bustos et al., 1989).

Exemplary nucleic acids which may be introduced to the carrot lines of this invention include, for example, DNA sequences or genes from another species, or even genes or sequences which originate with or are present in the same species, but are incorporated into recipient cells by genetic engineering methods rather than classical reproduction or breeding techniques. However, the term “exogenous” is also intended to refer to genes that are not normally present in the cell being transformed, or perhaps simply not present in the form, structure, etc., as found in the transforming DNA segment or gene, or genes which are normally present and that one desires to express in a manner that differs from the natural expression pattern, e.g., to over-express. Thus, the term “exogenous” gene or DNA is intended to refer to any gene or DNA segment that is introduced into a recipient cell, regardless of whether a similar gene may already be present in such a cell. The type of DNA included in the exogenous DNA can include DNA which is already present in the plant cell, DNA from another plant, DNA from a different organism, or a DNA generated externally, such as a DNA sequence containing an antisense message of a gene, or a DNA sequence encoding a synthetic or modified version of a gene.

Many hundreds if not thousands of different genes are known and could potentially be introduced into a carrot plant according to the invention. Non-limiting examples of particular genes and corresponding phenotypes one may choose to introduce into a carrot plant include one or more genes for insect tolerance, such as a Bacillus thuringiensis (B.t.) gene, pest tolerance such as genes for fungal disease control, herbicide tolerance such as genes conferring glyphosate tolerance, and genes for quality improvements such as yield, nutritional enhancements, environmental or stress tolerances, or any desirable changes in plant physiology, growth, development, morphology or plant product(s). For example, structural genes would include any gene that confers insect tolerance including but not limited to a Bacillus insect control protein gene as described in WO 99/31248, herein incorporated by reference in its entirety, U.S. Pat. No. 5,689,052, herein incorporated by reference in its entirety, U.S. Pat. Nos. 5,500,365 and 5,880,275, herein incorporated by reference it their entirety. In another embodiment, the structural gene can confer tolerance to the herbicide glyphosate as conferred by genes including, but not limited to Agrobacterium strain CP4 glyphosate resistant EPSPS gene (aroA:CP4) as described in U.S. Pat. No. 5,633,435, herein incorporated by reference in its entirety, or glyphosate oxidoreductase gene (GOX) as described in U.S. Pat. No. 5,463,175, herein incorporated by reference in its entirety.

Alternatively, the DNA coding sequences can affect these phenotypes by encoding a non-translatable RNA molecule that causes the targeted inhibition of expression of an endogenous gene, for example via antisense- or co-suppression-mediated mechanisms (see, for example, Bird et al., 1991). The RNA could also be a catalytic RNA molecule (i.e., a ribozyme) engineered to cleave a desired endogenous mRNA product (see for example, Gibson and Shillito, 1997). Thus, any gene which produces a protein or mRNA which expresses a phenotype or morphology change of interest is useful for the practice of the present invention.

Many useful traits are those which are introduced by genetic transformation techniques. Methods for the genetic transformation of carrot are known to those of skill in the art. For example, methods which have been described for the genetic transformation of carrot may include electroporation, electrotransformation, microprojectile bombardment, Agrobacterium-mediated transformation, direct DNA uptake transformation of protoplasts and silicon carbide fiber-mediated transformation. See, e.g., Khachatourians, G., et al., eds., Transgenic Plants and Crops, Marcel Dekker, Inc. (2002).

It is understood to those of skill in the art that a transgene need not be directly transformed into a plant, as techniques for the production of stably transformed carrot plants that pass single loci to progeny by Mendelian inheritance is well known in the art. Such loci may therefore be passed from parent plant to progeny plants by standard plant breeding techniques that are well known in the art. Examples of traits that may be introduced into a carrot plant according to the invention include, for example, male sterility, herbicide resistance, disease resistance, insect resistance, and enhanced nutritional quality.

PCR and Southern hybridization are two examples of molecular techniques that can be used for confirmation of the presence of a given locus and thus conversion of that locus.

G. DETERMINATION OF LYCOPENE CONTENT

For lycopene analysis of individual roots, individual root tips are diced, weighed and then ground to a fine slurry with an equal weight of RIO water. A sub-sample (about 1 gram) is weighed out into an amber extraction vial. An extraction mixture of acetone, methanol and hexane is added to the vial. The carotenoids are extracted by grinding with an IKA T25 Ultra-Turrax homogenizer. The hexane is separated from the other solvents by the addition of 1 M sodium chloride solution followed by centrifugation. The lycopene is measured by transferring the hexane phase to a cuvette and reading the absorbance at 503 nm on a Cary 1 spectrophotometer (Varian, Inc., Palo Alto, Calif.).

For bulk root analyses of lycopene content, fifteen to twenty carrots are diced, weighed then ground to a fine slurry with an equal weight of RIO water. A sub-sample (about 1 gram) is weighed out into an amber extraction vial. An extraction mixture of acetone, methanol and hexane are added to the vial. The carotenoids are extracted by grinding with an IKA T25 Ultra-Turrax homogenizer. The hexane is separated from the other solvents by the addition of 1 M sodium chloride solution followed by centrifugation. The lycopene is measure by analyzing the hexane phase on an Agilent 1100 HPLC system. Fifteen micro-liters of hexane extract were injected onto a Whatman Partisil 5 ODS-3 WVS column and separated using an isocratic solvent mix of acetonitrile, methanol, isopropanol, water (765, 90, 162, 36). Lycopene was quantified using an Agilent G1315B diode array detector (Agilent/Hewlett Packard) at 503 nm.

H. DEFINITIONS

In the description and tables herein, a number of terms are used. In order to provide a clear and consistent understanding of the specification and claims, the following definitions are provided:

A: When used in conjunction with the word “comprising” or other open language in the claims, the words “a” and “an” denote “one or more.”

Allele: Any of one or more alternative forms of a gene locus, all of which alleles relate to one trait or characteristic. In a diploid cell or organism, the two alleles of a given gene occupy corresponding loci on a pair of homologous chromosomes.

Backcrossing: A process in which a breeder repeatedly crosses hybrid progeny, for example a first generation hybrid (F₁), back to one of the parents of the hybrid progeny. Backcrossing can be used to introduce one or more single locus conversions from one genetic background into another.

Crossing: The mating of two parent plants.

Cross-pollination: Fertilization by the union of two gametes from different plants.

Diploid: A cell or organism having two sets of chromosomes.

Emasculate: The removal of plant male sex organs or the inactivation of the organs with a cytoplasmic or nuclear genetic factor conferring male sterility or a chemical agent.

Enzymes: Molecules which can act as catalysts in biological reactions.

F₁ Hybrid: The first generation progeny of the cross of two nonisogenic plants.

Genotype: The genetic constitution of a cell or organism.

Haploid: A cell or organism having one set of the two sets of chromosomes in a diploid.

Linkage: A phenomenon wherein alleles on the same chromosome tend to segregate together more often than expected by chance if their transmission was independent.

Marker: A readily detectable phenotype, preferably inherited in co-dominant fashion (both alleles at a locus in a diploid heterozygote are readily detectable), with no environmental variance component, i.e., heritability of 1.

Phenotype: The detectable characteristics of a cell or organism, which characteristics are the manifestation of gene expression.

Quantitative Trait Loci (QTL): Quantitative trait loci (QTL) refer to genetic loci that control to some degree numerically representable traits that are usually continuously distributed.

Regeneration: The development of a plant from tissue culture.

Self-pollination: The transfer of pollen from the anther to the stigma of the same plant.

Single Locus Converted (Conversion) Plant: Plants which are developed by a plant breeding technique called backcrossing, wherein essentially all of the desired morphological and physiological characteristics of a carrot variety are recovered in addition to the characteristics of the single locus transferred into the variety via the backcrossing technique and/or by genetic transformation.

Substantially Equivalent: A characteristic that, when compared, does not show a statistically significant difference (e.g., p=0.05) from the mean.

Tetraploid: A cell or organism having four sets of chromosomes.

Tissue Culture: A composition comprising isolated cells of the same or a different type or a collection of such cells organized into parts of a plant.

Transgene: A genetic locus comprising a sequence which has been introduced into the genome of a carrot plant by transformation.

Triploid: A cell or organism having three sets of chromosomes.

As used herein, a “control” carrot is a carrot line selected from the group consisting of Honkou Kintoki, Invicta, and Shinku Kintoki. In a preferred aspect, Honkou Kintoki is the control carrot line. A control carrot line is also grown under similar environmental conditions to the carrot line according to the present disclosure.

As used herein, “open-pollinated” refers to plants capable of breeding from a mixture of self and cross pollination. For example, open-pollinated plants are capable of self- or sib-pollinating and cross-pollinating.

As used herein, “cytoplasmic male sterility” refers to plants that are not capable of setting seed from self or sib pollination, but are capable of breeding from cross-pollination, due to the inability of the plant to produce pollen.

As used herein, “linkage” is a phenomenon wherein alleles on the same chromosome tend to segregate together more often than expected by chance if their transmission were independent.

As used herein, “Nantes” refers to one of the primary carrot varieties grown worldwide. The Nantes variety is generally characterized as a carrot line having sparse foliage that is weakly attached to the crown. The Nantes root is moderately long (between about 6-7 inches, or about 15 cm-18 cm) with a uniform diameter (between about 1-2 inches, or about 2.5 cm-5 cm) along its length. The root further has a rounded tip at maturity, and has a highly pigmented core, which has relatively succulent, brittle roots. The Nantes root also matures early (between about 55 days and about 100 days after sowing), and the roots are higher in sugars, but lower than average in terpenoids and dry matter making the roots less suitable for long-term storage. In addition, the surface of the root is thinner than many other varieties and scars easily.

As used herein, “red male carrot” refers to a carrot plant having an increased lycopene content that provides a source of pollen for fertilizing a female recipient carrot plant.

As used herein, an “orange male carrot” refers to a carrot plant having a root containing low or non-detectable levels of lycopene that provides a source of pollen for fertilizing a female recipient carrot plant. For example, orange male carrots produce roots having less than about 40 ppm, 30 ppm, 20 ppm, or 10 ppm lycopene. Examples of orange male carrot lines include S-D813B (Seminis Vegetable Seeds, Inc.), B3640M, B3080M, B3475, B8080, B5280, B6333, B5238, and B6274 (each available from the USDA).

As used herein, a “female parent” refers to a carrot plant that is the recipient of pollen from a male donor line. A female parent can be any carrot plant that is the recipient of pollen. Such female parents can be male sterile, for example, as a result of cytoplasmic male sterility. Cytoplasmic male sterility can be of the brown anther type, in which the anthers degenerate and shrivel prior to anthesis, and is based on S-cytoplasm and at least two recessive genes with complementary action. Cytoplasmic male sterility can also be of the petaloid type, in which five additional petals replace anthers, resulting from S-cytoplasm and at least two dominant genes with complementary action.

As used herein, a “marker” is an indicator for the presence of at least one phenotype or polymorphism, such as single nucleotide polymorphisms (SNPs), cleavable amplified polymorphic sequences (CAPS), amplified fragment length polymorphisms (AFLPs), restriction fragment length polymorphisms (RFLPs), simple sequence repeats (SSRs), or random amplified polymorphic DNA (RAPDs). A marker is preferably inherited in co-dominant fashion (both alleles at a locus in a diploid heterozygote are readily detectable), with no environmental variance component, i.e., heritability of 1. A “nucleic acid marker” as used herein means a nucleic acid molecule that is capable of being a marker for detecting a polymorphism, phenotype, or both.
